Hearing sense is one of the key elements which may have impact on the driver's task quality. This cross-sectional study investigates the hearing status of 500 truck drivers by pure tone audiometry (AC) in one of the cities in Fars province, Iran. Hearing threshold levels of the subjects were measured in frequencies of 500Hz-8000Hz. Screening and determination of permanent threshold shift (PTS) ...

OBJECTIVE The aim of this study was to assess the benefit of having preserved acoustic hearing in the implanted ear for speech recognition in complex listening environments. DESIGN The present study included a within-subjects, repeated-measures design including 21 English-speaking and 17 Polish-speaking cochlear implant (CI) recipients with preserved acoustic hearing in the implanted ear. The...

While there have been numerous studies in the field of speech enhancement, the majority of these studies have focused on noise reduction for normal-hearing (NH) individuals. In addition, no speech enhancement algorithms reported in the signal processing community have reported an improvement in intelligibility, with the exception of a recent study by Tsoukalas et al. [IEEE Transactions of Speec...

A 46-year-old white male diagnosed with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS) was seen for audiological testing 15 minutes following a sudden onset hearing loss in the right ear. The test battery included pure-tone audiometry, word-recognition testing, speech-recognition threshold (SRT) testing, immittance testing, and distortion-product otoacoustic emissions (D...

background acoustic trauma is an injury to the hearing mechanisms in the inner ear due to excessive noise. this injury is the most prevalent cause of sensorineural hearing loss in humans, especially from occupational exposure. previous studies have shown the essential role of free radical formation in the inner ear hearing loss caused by acoustic trauma. objectives this study was performed to d...

OBJECTIVES We investigated the normative data on the hearing threshold levels of Koreans with normal tympanic membranes and the prevalence of hearing loss (HL) and nonserviceable hearing using the data from the Korea National Health and Nutrition Examination Surveys (KNHANES) during 2010-2012. METHODS Data obtained from 16,673 participants ≥12-year-of-age with normal tympanic membranes who co...

Background: Diabetes mellitus and hearing loss are common public health problems. Sensorineural in Type 2 diabetes patients is an underestimated complication. The aim was to study the correlation between level of HbA1c degree sensorineural loss. Methods: It a cross sectional carried on 130 known cases T2DM, aged 25-50 years. Various confounding factors such as coexisting hypertension, ear disea...

OBJECTIVES The aim of the study was to assess the influence of short-term impulse noise on the size and dynamics of temporary threshold shift, which precedes permanent threshold shift, i.e. noise-induced hearing loss. It was hoped to use the findings for preventive activities. MATERIALS AND METHODS The study included 80 healthy subjects (160 ears), aged 19-23 years, divided into two groups: g...

This study describes a new noise suppression scheme for hearing aid applications based on the auditory masking threshold (AMT) in conjunction with a modified generalized minimummean square error estimator (GMMSE) for individual subjects with hearing loss. The representation of cochlear frequency resolution is achieved in terms of auditory filter equivalent rectangular bandwidths (ERBs). Estimat...
